Patent EP-0053645-A1 (EP)
Inventor: ZAVODSKY JAN
IPC: B65H63/032
Filed: 1981-01-05
Abstract: The opto-electric device has a radiation source (1) whose radiation is polarised by means of two crossed polarisation filters (4, 6), so that a dark field is produced and no radiation reaches the radiation receiver (7). A transparent yarn (11) causes a local, additional rotation of the polarisation plane, as a result of which the yarn (11) appears as a light zone in the dark field. The radiation receiver (7) then does not trigger any actuating signal for deactivating the machine (10). In the absence of yarn, the radiation receiver (7) produces, via a switching apparatus (8), an actuating signal for the actuating element (9) for deactivating the machine (10). <IMAGE>

Abstract: A telecentric optical fiber connector (13), shown in Fig. 1, wherein light from an optical fiber (11) is emitted from the connector lens (18) in a comparatively large diameter parallel beam (19), including two primary components: an integral optical quality plastic connector body (17) having an annular planar reference surface (26) substantially perpendicular to an optical axis (46) (Fig. 3). A convex lens surface (18) is molded, recessed inward from the reference surface (26). The body (17) is substantially cylindrical, with exterior means (55) (Fig. 4) thereabout so that it can be engaged with a similar body. The opposite axial end of the body (17) has a central cilindrical cavity (52) (Fig. 3) therein which extends to a point (16) which is one focal length from the lens surface (18). A fiber holder (14), which holds an optical fiber (11) centrally within an axial hole (29), abuts an end of the fiber (11) against the point (16) one focal length from the lens surface (18), and can be engaged with index-matching material.

Abstract: A method for the recrystallization of an activated rare-earth oxyhalide phosphor is disclosed. The method comprises recystallizing the phosphor by firing a uniform mixture of the finely divided phosphor and flux in an inert atmosphere. The flux contains a magnesium halide from which more than the readily removable water has been removed. One particularly preferred phosphor made by the method is a lanthanum oxychloride phosphor coactivated with bismuth and ytterbium. This phosphor made by the present method had high speed and low afterglow.

Abstract: Nouveau systeme de resine a matrice bis-imide comprenant entre 50 et 95% en poids de bis-imides a liaison ethylenique non saturee, de preference un melange a bas point de fusion d'une majeure partie de maleimide d'amines aromatiques d'une petite portion de maleimide d'une amine aliphatique et entre 5 et 35% en poids d'un agent de reticulation a basse temperature de double insaturation telle que le divinyle benzene qui gelifie le bis-imide aux basses temperatures. Cela permet de reduire les contraintes entre la resine de la matrice et la surface de la fibre de renforcement, reduisant ainsi la tendance a la formation de micro-fissures. La formation de micro-fissures est reduite encore plus et la resistance transversale est augmentee par addition de 0 a 15% d'elastomeres compatibles avec la resine et l'agent de reticulation. La viscosite a temperature ambiante, la resistance thermique et la densite de reticulation sont ameliorees par la presence de 0 a 10% d'un agent de polymerisation trifonctionnel.

Abstract: Une source de pulverisation a magnetron circulaire utilise une anode centrale (10) entouree par une cathode annulaire (12) ayant une configuration conique generalement inversee. La structure de l'anode forme une anode composite et une piece polaire interieure magnetique (15) qui est alimentee avec un potentiel de terre ou proche de celui-ci. Une piece externe polaire magnetique (72) entoure de maniere concentrique la cathode annulaire. Cette piece polaire externe est isolee electriquement de la cathode, et maintenue a un potentiel de terre ou proche de celui-ci. La cathode fonctionne a un potentiel negatif de plusieurs centaines de volts par rapport a la terre. La cathode est maintenue en place par des nouveau moyens de retenue (60, 61, 65 et 66) et possede une nouvelle configuration en coupe transversale (13, 62, 63, 64, 67, 68 et 69). Un flux magnetique est cree soit par des aimants permanents (33) ou par des electro-aimants (non illustres) ou par une combinaison des deux situee a l'exterieur d'une chambre a vide dans laquelle la source de pulverisation fonctionne. Des lignes de champ magnetique (95) passent depuis la piece polaire externe (72) et au travers de la cathode (12), sortant de la surface de pulverisation (13) a proximite du bord externe de la cathode. Ces lignes de champ magnetiques forment un arc par dessus la cathode (12) en passant directement vers l'anode centrale (10) sans entrer de nouveau dans la surface de pulverisation non erodee (13) de la cathode. Dans une geometrie circulaire, ces lignes de champ magnetique en forme d'arcs forment un tunnel sans fin pour y contenir une decharge luminescente ou effluve. Le tunnel ainsi forme est un nouveau tunnel magnetique modifie dans lequel des electrons sont reflechis electrostatiquement depuis la surface cathodique a proximite du bord externe de la cathode et sont reflechis par reflexion magnetique au voisinage du bord interne. L'utilisation de ce tunnel magnetique modifie ameliore les caracteristiques d'impedance electrique de l'effluve ainsi que

Abstract: Es wird ein Verfahren und ein entsprechendes Stanzwerkzeug zum abfallfreien Ausstanzen von Packungsstreifen sowie entsprechend erzeugter Packungsstreifen, z.B. sogenannten Durchdrückpackungen, vorgeschlagen. Diese Durchdrückpackungen bestehen aus einem Folienstrang, der aus einer Näpfe zur Aufnahme von Tabletten, Dragees od.dgl. enthaltenden Unterfolienbahn und einer die Näpfe verschließenden Deckfolienbahn besteht. Zur störungsfreien Weiterbearbeitung und zur Vermeidung von Verletzungen weisen die einzelnen Packungsstreifen (15, 16, 17) abgerundete Ecken (30) auf. Zur Vermeidung von scharfen, hakenförmigen Vorsprüngen, die beim abfallfreien Ausstanzen der Packungsstreifen (15, 16, 17) entstehen, wenn ein Versatz im Vorschub des Folienstranges eintritt, ist die Stanzkante (19) des Stanzwerkzeuges (18) so ausgebildet, daß beim Ausstanzen eines Packungsstreifens (15, 16, 17) diese Stanzkante (10) die Kante des zuvor ausgestanzten Packungsstreifens (15, 16, 17) so schneidet, daß an der in Bewegungsrichtung vorn liegenden Kante (21) des Packungsstreifens (15, 16, 17) ein stumpfer Winkel entsteht. Durch diese Ausbildung der Stanzkante (19) des Stanzwerkzeuges (18) ergeben sich Packungsstreifen (15, 16, 17), die ein wesentlich gleiches äußeres Erscheinungsbild aufweisen, wobei trotz unterschiedlichem Vorschubversatz alle vier abgerundeten Ecken eines Packungsstreifens (15, 16, 17) den gleichen Radius haben.

Abstract: Bei vorliegender Aufsteckung für eine Spinnmaschine sind mindestens zwei parallel verlaufende Reihen rotierbar aufgehängter Luntenspulen (11, 12) nebeneinander aufgereiht. Bei Ringspinnmaschinen werden bei solchen Aufstekkungen sich in der Längsrichtung der Maschine horizontal erstreckende Luntenumlenkstangen verwendet. Die von den Luntenspulen zu den Streckwerken verlaufenden Lunten werden zur Führung derselben um die Umlenkstangen geführt. Befindet sich die Stange hinter den Spulen, so ist das Herumziehen der Lunte um die Stangen äußerst beschwerlich, und es besteht außerdem die Gefahr, daß die Lunten Beschädigungen erleiden können. Befindet sich die Stange weiter vorn, so ist das Auswechseln der Spulen ein mühsamer Vorgang. Diese Nachteile sollen dadurch vermieden werden, daß eine Reihe von stabförmig geformten Haltern (20) angeordnet ist, welche sich hinter der vordersten Spulenreihe befinden, mit ihrem einen Ende fest montiert sind und an ihrem anderen Ende mindestens zwei Führungen (27, 28) für Lunten (13, 14) aufweisen, welche Lunten (13, 14) unmittelbar von den Luntenspulen (11, 12) über die Führungen (27, 28) zu den Streckwerken (17) verlaufen.
